Albus Dumbledore sighed as he massaged the sides of his temples. It was 1998, the school year had just ended, and a few Hogwarts graduates had just joined the Order.

In fact, they were currently in a meeting, debating what they should do about Voldemort.

"Albus, let's just use that spell I told you about last year," Moody grumbled. "It'll make this so much easier."

"Easier, Alastor? You and I both know that it could very well cause so much more chaos than even Voldemort is." He replied, looking up from the table that he had been absently staring at as he contemplated the war.

"Yes but the spell's a gamble, we know that. Might as well try, at least it'll bring a person to defeat Voldemort." Moody muttered, new magical eye whirring around in it's socket.

"What spell?" Lily Evans, soon to be Potter, asked. A truly delightful girl, always interested in knowledge.

Before Moody could reply, Albus was already explaining. "Alastor discovered a spell in an ancient tome that would summon a person from an alternate universe that has the power to do the thing you specify when casting the spell. There are limits to your specifications, of course, such as you cannot make them cater to your every whim, but those are the basics of the spell."

Sirius Black perked up, "That's a great spell! We can summon someone to deal with Voldemort and be done with it." He said excitedly, beginning to grin.

Lily rolled her eyes and smacked the back of his head. "You idiot, you do realize this person could be another dark lord, correct? One summoned to defeat Voldemort, just to take over our world afterwards."

Sirius slumped back down, possible ramifications of using the spell sinking in. A few other order members started a debate on whether or not to use the spell.

The decision only just slipped by. They should.

Albus sighed and pulled out his wand. "Alright, then back away everyone." He began the long and arduous process of casting the spell, and a little under forty-five minutes later, there was a bright flash of light, and a figure landed on the table.

They weren't able to tell anything about the figure, as the moment they landed (in a sort of couch as if expecting attack) they had purposefully rolled off the side of the table and then leapt up,wand in hand, leveled at them all.

Looking at the figure, a woman, everyone studied her. Eighteen, perhaps, young but obviously experienced. She had black hair, cut short so it only reached her ears (it was a mess but was pinned back with small black hairpins), hard green eyes, a lightning bolt scar a little off center on her forehead, and three scars of equal length, width, and distance apart spanning from her left temple to curve beneath her chin, ending at her collar bone. They looked disturbingly like the claw marks of a large creature.

There was a minute of absolute silence, a few order members' wands out, prepared in case their new guest was hostile. But she didn't seem to be in any rush to curse them, instead taking in the situation around her, though it was obvious that she would curse, no questions asked, at the smallest sign of ill intent towards her.

Albus spoke before any curses could be actually cast. "Hello, my name is Albus Dumbledore, and, basically, we just summoned you from an alternate dimension to help us fight a Dark Lord named Voldemort."

The girl's gaze turned to him, though her attention was focusing on the room at large. "Is that so?" She had a melodious voice, a fair few of them noted, Sirius Black in particular.

Sometimes Albus wish he hadn't learned passive legilimency. The amount of guys that now immediately trusted her due to her looks and pleasing voice was, quite frankly, disheartening.

Judging by the very slightly amused, annoyed, and yet commiserating look she gave him, that only Albus noticed, she agreed.

That was interesting. So she knew passive legilimency as well, or was she just used to such things?

Either way, Albus needed to reply to her question, and he did. "Indeed, we used a spell called the Producat in Salutem."

Recognition dawned on her face and she glanced around at everyone, no longer distrustful but curious, and obviously holding herself back from… questioning (hugging?)… someone, before her face became expressionless again.

The girl cast a tempus charm, rolled her eyes, and have a muttered 'fabulous' under her breath before conjuring a chair, stowing her wand away up her sleeve, sitting down, and leaning back, kicking her feet up on the table and crossing her legs. "Well this is wonderful, now, can someone tell me the general events as of late? Aside from Voldemonkey - I already got that."

James asked a question at the same time as Elphias Doge. "Who are you?" That was James.

"Voldemonkey? Are you insane?!" That was Elphias.

The girl was amused. "Well, Mr Doge, I suppose you could say I am," here she began to mutter, "I mean no sane person backflips off a building with multiple fractures in her spine." Then she continued to speak normally. "Besides, all the best people are." Then she turned to James and her amusement became a little more pronounced. "And funny you should be the one to ask that, Dad."

"What?!" James' eyes were wide, shocked, and Sirius literally fell out of his chair. Remus began choking on his own spit, and Lily froze in her seat. No one else was much better.

Albus raised an eyebrow at the outwardly smirking girl. "You knew this would cause chaos," he said as everyone began to quiet down.

They all turned to the girl, who snorted, "Yep." She glanced around at all the shocked faces and seemed to take pity on them. "The name's Harlequin Lilia Potter, I prefer the nickname Harri, and, while I am a Batman fan, please don't joke that I'm Harley Quinn."

"Who?" Lily asked, confused.

Harlequin grinned, "She's a character that first appears in 1992. She's depicted as the female sidekick of the Joker and is absolutely ensnared by him, sort of willfully blind to his insanity and lack of affection towards her." Here Harlequin leaned back, considering, "I suppose she's rather like Bellatrix, though Bellabitch is very aware of Voldewhore's insanity and lack of affection."

There were more shocked chokes. "Why do you make fun of their names?" Minerva McGonagall asked, "You realize if they find out, you'll be killed?"

Harlequin let out a snort of laughter, "Where do you think these came from?" She gestured to the three scars across her face. "I called Fenrir Greyback a cute little puppy. To his face. On the full moon when he was transformed. This was his revenge, seeing as he couldn't bite me."

"How come?" Moody asked, curious. This may be a way to ensure no werewolves ever bit another person.

Harlequin smirked at him. "You bite me and you die. It's as simple as that."

Remus spoke up here, "But it's Greyback, he doesn't care for your skill, he'd bite you anyway."

Harlequin gave him a serious look. "No you don't understand. It has nothing to do with my skill. Literally, you bite me and you die. My blood is toxic."

"Prove it." Mundungus Fletcher muttered.

Harlequin gave him a dark grin that sent shivers down everyone's spine as she leaned her chair forward with a small thud, putting her feet back on the ground and sitting up properly. "Gladly." She pulled a dagger from her boot and sliced her palm. As the blood flooded her cupped hand, everyone noticed a silver and a gold liquid within it as well. Her blood was literally red, silver, and gold all mixed together.

"Trippy," someone muttered, though Albus didn't pay attention to who.

The blood splashed onto the table, and turned entirely silver, and suddenly everything that touched it began to burn away. The blood on her hand turned gold, then disappeared, leaving a completely healed hand. Harlequin vanished the still-silver blood on the table and turned to Mundungus.

"Proof enough for you?" She inquired calmly, as if she didn't just terrify everyone.

"What… what was that?" Sirius asked, shaken.

"The silver was basilisk venom, the gold was Phoenix tears." Harlequin leaned back again, returning to her previous position and absently spinning the dagger in her hands.

It was a strange one, the blade was bone white, and the hilt was silver. There was a leather grip around where her hand would go, and had a small inlay of emeralds set at the cross between the handle, hilt, and blade. It was elegantly crafted, and was obviously custom made.

"Who made your dagger? And what is the blade made of?" Albus asked curiously.

Harlequin glanced at it, then gave a small snort. "I made this myself, and the blade is a carved Basilisk fang."

They all stared. She gave them all a deadpan look. "Oi, I'm not joking here." She continued to spin it in her hands.

"Why did you cut yourself with it?" Lily asked, eyes wide in shock.

Harlequin shrugged, closing her eyes and tilting her head back. "I've already got Basilisk venom eternally running through my veins. It's not like this'll hurt me anymore than a regular dagger." Here she opened one eye to consider them all. "That being said, don't touch this dagger, as even touching a fang can be lethal- if you have an open cut near where you touched the fang or come into contact with one anytime after without taking the proper measures to clean yourself of the venom- and I make a point to constantly coat this dagger in venom, so as to enable its continued danger to everyone that isn't me."
